ABSTRACT The use of desiccants allows to anticipate cowpea harvest at a time closer to physiological maturity. The desiccants saflufenacil and flumioxazin promote the drying and falling of leaves and loss of water from seeds. This study aimed to evaluate the effects of saflufenacil and flumioxazin doses applied to the cowpea crop on the production and quality of seeds at harvest and after storage for six months. Two experiments were carried out in a split-plot design (5 × 2). In the first experiment, the main factor consisted of saflufenacil doses (0, 25, 50, 100, and 150 g ai ha-1), while the second factor consisted of evaluation periods (after harvest and six months after harvest). In the second experiment, the main factor consisted of flumioxazin doses (0, 10, 20, 30, and 40 g ai ha-1) and the second factor consisted of the same evaluation periods. The treatments were designed in randomized blocks, with four replications. Saflufenacil application from 25 g ha-1 compromised the yield components and technological quality, while flumioxazin doses did not affect the yield components. Storage at 20 °C for six months decreased the physiological quality of seeds. Flumioxazin application at cowpea harvest promoted uniformity of maturity and harvest anticipation, without compromising the physiological quality after harvest.

Abstract: The aim of this study was to evaluate the effects of pre-harvest desiccant herbicides on the yield and the physiological and technological quality of cowpea seeds after harvest and after storage. The experiment was conducted in a randomized block design with four replications. A split-plot design (6 × 2) was composed of the desiccant herbicides flumioxazin (30 g ai.ha-1), glufosinate ammonium (500 g ai.ha-1), paraquat (400 g ai.ha-1), saflufenacil (70 g ai.ha-1), and carfentrazone (24 g ai.ha-1) and an untreated control, as well as two seed evaluation periods, at harvest and six months after h arvest. Desiccants were applied at the R5 stage. The desiccants affected the yield, classification, color, and physiological quality of seeds of ‘BRS Guariba’. The glufosinate ammonium and paraquat herbicides compromised seed physiological quality. Flumioxazin did not affect seed yield components, color, and physiological quality. Storage at 20 °C for six months affected seed physiological quality.

The use of fungi in seed treatment can improve the plant's physiological characteristics. The aim of this study was to evaluate the influence of the use of Trichoderma harzianum on the physiological quality of bean seeds. The experiment was set up and conducted in the forest seed laboratory of the Federal University of Western Para, in a randomized design, using 4 procedures on the basis of a colony forming unit (CFU): T1 (0 CFU), T2 (4 x 109 CFU), T3 (8 x 109 CFU) and T4 (12 x 109 CFU), with 5 repetitions. Germination percentage (G%), germination speed index (GSI), hypocotyl length (HL) and radicle length (RL) were evaluated as variables. The data were analyzed by variance analysis and the averages were compared using the Tukey test (p≤0.05), in addition to the regression analysis, using the Minitab© version 18 statistical software. There were differences between the germination percentage tests, in which T2 obtained 100% of germinated seeds, for GSI it was observed that T2 and T3 were equal and superior to the other treatments, while for RL T1 and T2 obtained the best results, however, for HL there were no statistical differences between treatments. T2 was more efficient in the physiological quality of seeds to germination percentage and germination speed index

ABSTRACT To obtain seeds of high physiological quality, it is of paramount importance to define the ideal harvest moment, which oftentimes corresponds to the period when the physiological maturity is reached. This experiment aimed to study the maturation process and determine the best harvest season of maroon cucumber fruits (Liso Gibão cultivar), in order to reach the maximum physiological seed quality. The flowers were labeled during the anthesis and the fruits harvested at 14, 21, 28, 35, 42, 49 and 56 days after the anthesis (DAA). The fruits had their visual aspects registered by photography analysis and, later, the seeds were extracted for physical (water and dry matter contents) and physiological (germination, seedling emergence, emergence speed index, accelerated aging and electrical conductivity) analyses. It was observed that the seeds reach the maximum dry mass (8.08 mg seed-1) between 47 and 49 DAA. However, the seed physiological maturity, characterized by a maximum germination (70 %) and vigor, occurs at 56 DDA. The best season to harvest seeds with a higher physiological quality takes place from 49 to 56 DDA, when the fruits present a yellowish color.

Melon are one of the most popular fruit commodities, but, despite the demand, its production in Indonesia has declined. One measure that can be used to optimize the quality of melon fruit is to trim off the leaf buds and arrange the position of fruiting on the stem, and this study, using the golden melon cultivar ‘Apollo,’ aimed to identify the effects of leaf bud trimming and fruit position arrangement in improving the quantity and quality of the fruit harvest. The experiment was conducted from March to May 2018 in the greenhouse of Food Crop and Horticulture Agribusiness Development (UPT Pengembangan Agribisnis Tanaman Pangan dan Hortikultura), in Lebo, Sidoarjo, Indonesia. It was based on a split-plot design, with leaf bud trimming as the main factor, consisting of two groups (trimming or not trimming), and fruit positions as the secondary factor, consisting of four stages, all repeated at four different time intervals. A correlation was found between leaf bud trimming and fruit position arrangement toward the number of leaves. However, the treatments did not affect the growth and yield of the plants, but did have a significant effect on fruit weight, sweetness, and volume. It was concluded that trimming off the leaf buds and arranging the fruiting position on golden melon plants can increase the quality of fruits, with the treatment involving trimming combined with arranging fruiting on the twelfth–thirteenth segment showing the best results.

Physiological Quality

The objective of this work was to evaluate the physiological quality of cowpea seeds and the economic viability of storage in different types of packaging and with different chemical treatments. Seeds were submitted to one of the following chemical treatments of active ingredients: fipronil; fipronil + pyraclostrobin + thiophanate methyl; and fludioxonil + metalaxyl. Seeds without chemical treatment constituted the control. Seeds were placed in permeable cotton bags, permeable raffia bags, semipermeable kraft paper bags, and impermeable PET bottles. The following were evaluated: seed moisture content; germination test; first germination count; germination speed index; hypocotyl length; root length and hypocotyl dry mass and root dry mass. Cost analysis of treatments was also performed. The physiological quality of cowpea seeds was more markedly reduced under storage conditions in permeable packages with fludioxonil + metalaxyl treatment. Impermeable packaging without chemical treatment decreased deterioration of physiological quality in cowpea seeds and is economically viable for a storage period of up to 90 days.

During dry seasons, equines are traditionally fed hay. However, if not prepared under favorable climatic conditions and if not properly stored, hay does not preserve its nutritional value. The aim of this research was to evaluate the chemical composition in Stylosanthes guianensis cv. Mineirão and Estilosantes Campo Grande hay varieties, used to feed equines over 225 days of storage. Treatments consisted of Stylosanthes guianensis cv. Mineirão and Estilosantes Campo Grande hay varieties, assessed at six moments of storage: 0, 45, 90, 135, 180, and 225 days. The experiment followed a completely randomized split-plot design. In the comparison between varieties, differences (P0.05) over the 225 days of storage. The storage period had little impact on the nutritional quality of the assessed hays. The Stylosanthes guianensis cv. Mineirão and, mainly, Estilosantes Campo Grande hay varieties have potential to be used in equine diet.

Field experiments were conducted on an Oxisol with pH 5.0 in northwestern Puerto Rico in an attempt to determine whether the time interval between liming and cropping affected yields, yield components, and other plant characters. Six lime-cropping interval treatments were tested with two cultivars of succeeding crops of field beans and corn in a split plot design. Two cultivars were used as indicator crops in each case. The liming-cropping intervals ranged from planting immediately after liming to planting 10 months after liming (liming on a bimonthly basis). No significant yield differences attributable to treatments could be detected for either crop. In the same fashion, no significant differences were obtained on the various yield components and plant characters studied except for the fact that the 27R fieldbeans from plots limed 10 months prior to planting were smaller than those from plots limed just before planting. The effectiveness of liming Oxisols with pH 5.0 seems not to depend on the time interval that elapses between liming and planting.

A field study was conducted to evaluate the date of sowing of groundnut (<italic>Arachis hypogaea</italic> L.) during <italic>kharif</italic> 2009 and 2010. Experiment was laid out in split-plot design by assigned dates of sowing (20 April, 15 May, 9 June and 4 July) and varieties (‘HNG 10’ and ‘TG 37A’ ) in main plots and four fertility levels (without fertilizers, 20 N + 40 P<sub>2</sub>O<sub>5</sub>, 30 N + 60 P<sub>2</sub>O<sub>5</sub> and 40 N + 80 P<sub>2</sub>O<sub>5</sub> kg /ha) in sub-plots. Yield components of semi-spreading variety ‘HNG 10’ were statistically at par with each other at different dates of sowing from 20 April to 9 June. Harvest index in both the varieties was observed significantly higher in 4 July sowing. The results of the study showed that significantly higher crop stand at harvest was observed in 9 June and 4 July sowing than all other sowing dates and variety ‘TG 37A’ flowered significantly earlier than ‘HNG10’. Significantly higher yields were recorded in 30 kg N+60 kg P<sub>2</sub>O<sub>5</sub> /ha which was statistically at par with 40 kg N+80 kg P<sub>2</sub>O<sub>5</sub> /ha. On the basis of economics, variety ‘HNG 10’ of groundnut recorded significantly higher net re urn ( 61843/ha) when sown on 9 June.
